In certain countries it's normal for businesses to charge customers based on their economic status.
Think of it as a "hidden" tax on
stupidity wealth.

If a customer look wealthy or rich, he's charged higher than normal.
As if a buyer couldn’t just turn around and go to another seller with reasonable prices? This is a free market involving two parties, not a situation where one side can unilaterally dictate
unfavorable terms.
In this situation, the "king of the hill" is the person who has the least need for what the other party possesses (whether it be a good \ service or money).
If he looks poor, and possibly bargains really hard, he could end up getting a fair deal, sometimes below the cost price or eiven free of charge, typically for beggars who have nothing atall to pay... yet such model remains profitable.
So, you’ve uncovered the magic formula for success in the marketplace: trying to haggle to secure a better price. And this approach is open to everyone, regardless of the size of their wallet.
Customers who don't get the idea may feel cheated and probably warn others to avoid such places.
If you don’t like it, don’t "eat" it. No one is forcing you to buy at inflated prices (other than your own inner idiocy).
Others are understanding enough and happy to pay especially since the goods and services are relatively cheap compared to wealthy places.
Of course, markets differ, but it is one’s personal income level that has a greater influence on "understanding". It is highly unlikely that an impoverished person would "understand" an approach where they are charged three times as much, simply because the seller deemed it an acceptable solution for them at that particular moment.
In Rwanda for example, I watched a foreigner trying to persuade fellow visitors to consider this fact, and for the sake of the poor.
If you want to help, just give money directly to the poor. Why complicate things?

I believe the model is what sustains the poor... businesses are willing to keep price extremely low because of poverty.
The only thing business cares about is profit (it is precisely for this reason that any business comes into existence). Everything else is just fairy tales.
If some end up not being profitable, they are still able to survive from other people's helps.
Well, then the business simply closes down.

Get rid of any illusions: business is an extremely aggressive environment (it is difficult to compete) with no room for charity.
I'm considering this topic because of the poor and needy. When we propose ideas that can help keep businesses profitable, we are burdened by the fact that they are probably going to be at the detriment of the poor and needy. So, for conscience sake, we focus on workable ideas that support the poor without affecting businesses negatively.
Do you own a business? I’m certain that once your family’s well-being and your children’s future depend on your own business, you’ll start to view the idea of "supporting the poor" at the expense of that business in a very different light.
You’re just a poor person who wants to "survive" without doing any work, by living off someone else’s business - is that it?
